Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Aluminum is more lightweight than steel and stainless steel and has good corrosion resistance.
For technical drawings and 3-D models, click on a part number.
Open duct can be cut with snips prior to installation. The seam snaps together without tools.
Adjustable-angle elbow connectors can be used at an angle or straight.
Duct Flanges
Bolt flanges to equipment to start a run of duct. They can also create secure connections between two duct ends by mounting a flange to each end and then joining the flanges.
Aluminum flanges have good corrosion resistance in wet environments, and weigh less than steel and stainless steel flanges.

Bend-and-Stay Metal Duct Hose for Air
- Very Flexible
- Compatible Clamps: Worm-Drive Clamps
- Temperature Range: -100° to 435° F
Unlike fabric duct hose, this lightweight aluminum hose can bend around corners and hold its shape. Hose is not for continuous flexing. One end of the hose is crimped; insert the crimped end into another piece of duct hose and secure with a clamp to create longer lengths. The hose may need support once the length exceeds 6 feet.

Proportional HVAC Damper Actuators
This actuator provides better control than incremental actuators because it is constantly being positioned in response to duct airflow requirements. Use to automatically adjust dampers to regulate airflow. It attaches to the damper shaft to rotate it open and closed when signaled by a controller (not included). Actuator can be set to return the damper to an open or closed position if the power fails. Use the crank for precise adjustments.
